Open Meta Ads Editor in the side menu to get to the Bulk Publish Ads page. On the Create Ad tab, use the Search Account field to filter and select one or more Ad Accounts (hold Ctrl on Windows or Cmd on Mac to select several), then select one or more Campaigns. If you want, open Select Ad Sets (optional) to choose specific ad sets: by default, active ad sets are already selected. Fill in the optional fields (Ad Name, Ad Add-on, Website URL, Headline, Primary Text), choose the files under Creatives (Images or Videos), and set the Ad Status (Paused or Active). Click Create Ads and follow the progress in the list below: each ad appears with a status of Queued, Processing, Published, or Error. Each media file becomes one ad in every selected ad set.
